【摘要】 光子交换技术是解决高速的光纤传输系统和低速的电子交换系统之间速度失配的根本措施。文中提出了无阻塞自由空间光子交换榕树网络的拓扑结构与实现方案，并采用互连网络拓扑等价的图分析法研究了无阻塞榕树网络与可重排Ｂｅｎｅｓ网络的拓朴等价及其多样性。为拓展无阻塞榕树网络在光子交换系统及多处理计算机系统的潜在应用提供了理论依据。更多还原

【Abstract】 Photon switching technology is a fundamental solution to the speed unmatch between optical fibre system with high transmission speed and electronic switching system with slow switching speed. This paper proposed the topological structure and optical implementation scheme of free-space photon switching nonblocking banyan network. Topologically equivalence and its varieties of nonblocking banyan networks with rearrangeable Benes network were studied with the help of the graph analysis methood (GAM),which theoretically developed the potential applications of nonblocking banyan networks in photon switching systems and multiprocessing computer systems.更多还原
